Product areas

Core Integration APIs is the shared API layer for discovery, quote, order creation, order query, and order-status webhook handling. On-ramp APIs and Onchain Payment APIs both use this shared layer.

• On-ramp APIs — Let users buy crypto through a Binance-powered hosted checkout flow and receive crypto to the configured destination.
• Onchain Payment APIs — Let users pay through Binance Pay Onchain using supported crypto or Binance balance sources, with settlement sent onchain to a supported destination.
• Merchant Payout to Binance Account APIs — Let platforms simplify crypto payouts to a user's Binance account through user-authorized Binance deposit address handling.
• Compliance and Refund Data Sharing — Access approval-based user and refund data fields for eligible compliance, risk, refund, reconciliation, or regulatory-support workflows.
